GCP configuration for migration from zone to region
Prior to release 10.1, the GCP provider was configured by selecting zone(s). With this release a checklist is provided to select the regions. Once the provider is configured with regions, the assets from all the zones from the configured region are discovered.
If Snapshot Manager is upgraded from any prior release, all the zonal configurations are moved to regional. Following are the examples for different scenarios of migration from zone to region after upgrading:
:
If one single provider configuration is present before upgrade with us-west1-a and us-east1-b zones, then after upgrade the configuration would change to us-west1 and us-east1. Along with the us-west1-a and us-east1-b zones, assets from the other zones which are part of the us-west1 and us-east1 regions can also be protected.
:
: Prior to upgrade if there are two GCP providers configured as follows:
GCP1 is configured with zones: us-east1-a, us-west1-a
GCP2 is configured with zone: us-central-a
After upgrade the above configuration would change to regions as follows:
GCP1: us-east1 and us-west1
GCP2: us-central
Note:
After updating configuration from zonal to regional, no region is duplicated in the different providers.
: Prior to upgrade if there are two GCP providers configured as follows:
GCP1 is configured with zones: us-east1-a, us-west1-a
GCP2 is configured with zone: us-central-a and us-east1-b
After upgrade the above configuration would change to regions as follows:
GCP1: us-east1 and us-west1
GCP2: us-central and us-east1
Note:
After updating configuration from zonal to regional, us-east1 region is duplicated in GCP1 and GCP2 providers.
Resolving regional conflicts after upgrade
After upgrade, there is a possibility of conflicts in the regions if:
there were multiple providers added in the single Snapshot Manager server
Or
if there were multiple Snapshot Manager servers registered to the single NetBackup master server
Following are examples for resolving the conflicts:
Example 1:
For GCP1: us-east1 and us-west1
For GCP2: us-east1 and us-central
User can remove us-east1 from any one of the above configuration by using the option in the providers tab.
If conflict occurs between multiple Snapshot Manager servers, then perform the following:
Add new provider configuration, GCP3 for the regions that are not conflicting. For example, us-west1
Delete GCP1 to remove the conflicts for regions between two Snapshot Manager servers.
Note:
If there are multiple Snapshot Manager servers registered to single NetBackup, contact Veritas support team for upgrade.
Example 2:
For GCP1: us-east1 and us-west1
For GCP2: us-east1
User can remove us-east1 from GCP2 by using option from tpconfig command.
Example 3:
For GCP1: us-east1
For GCP2: us-east1
User can remove any one provider configuration by using option from tpconfig command.
